To all mechanics and engineers. Please use it as an aid in the design of electrical work. Automatically selects cable and breaker sizes when motor and heater ratings are selected. [MOTOR]TAB First, select the target low-voltage three-phase squirrel-cage induction motor voltage. Next select the motor capacity (kW). Then, the following information is output to the list. ・Motor rated current ・Motor starting current ・Thermal rating ・Cable size for direct insertion (or StarDelta primary side) ・Cable size of Star Delta secondary side ・Breaker rating *If the wiring distance is long, consider the voltage drop and select a size larger than the displayed cable size. [HEATER]TAB First, select the heater specifications and voltage. Next select the heater capacity (kW). Then, the following information is output to the list. ・Heater rated current ・Cable size ・Breaker rating
